1. c4 {These days the top players try to mainly surprise their opponents in
the opening and to avoid the heavy home preparation. To get some psychological
advantage too. This aproach is quite unpleasant against a player who is not
doing well in the opening. And Anand chooses the English opening which he
plays very rarely.} e5 2. g3 c6 {Adams also replies with a surprise in return.
He had used the reversed Alapin in 2008 and for Anand this is already new.} 3.

I know, right? While a Buy Archeage Gold thin drive is cool and all, I'd much rather have more space in something the size of a deck of cards than less space in something slightly smaller. Even my caveman mind can understand that if you make something that Archeage Gold has 1/4 the capacity of something else, it Cheap Archeage Gold will probably be 1/4 smaller.
